I am working on Package AT&T Global Network client 5.06, where network plug & play driver have to be implement, that is getting install from the source with the service named ABVPN2K , where it installs 2 plug & play driver one is " Broadcom NetXtreme Gigabit Ethernet- Net Firewall miniport Interface" and 2nd one is "WAN Miniport[IP] - Net Firewall miniport Interface", Can any one knows how to implement these service. During the installation i found 2 inf files having the information about installaing this service, i have tried to implement the service through that INF using rundll32.dll API, but it doesnt works, may be the implementation is wrong, please help me out to implement the same

I have tried with Installing the driver(ABVPN2K-IPSEC) driver,But MSI installation is getting Rollback. As of original setup is installing miniport driver for "Broadband NetXtream Gigabyte Ethernet-Net Firewall Miniport Interface" and "WAN miniport (IP)-Net Firewall Miniport Interface".
Where it has two infs, one miniport INF and second one is protocol INf. and in original setup it is getting installed with one EXE called xpinst.exe having having 5 arguments as <-Filter> <Protocol Inf> <Miniport Inf> <Protocol Component Id> <Miniport component id>. Means using the Difxapp i have to provide both the inf in porper order, but it is not working out.I am not able to identify these agrument also properly, if any one knows the usage of this xpinst.exe with this arguments please let me know.
